STRAW-BURNING STOVE.

SPECIFICATION forming part of Letters Patent No. 425,713, dated April15, 1890.

Application filed April 4, 1889. $erial No. 306,037- (No model.)

To all whom it may concern:

Be it known that we, JOHN REUBEN TAOEY and JOHN SHARKEY, residing atWinnipeg, in the county of Selkirk, Province of Manitoba, and Dominionof Canada, have invented certain new and useful Improvements inStraw-Burning Stoves, of which the following is a specification.

Our invention has for its object to provide a suitably-constructedstraw-burning stove more especially adapted for burning as fuel hay,flax, or other material made into compressed shape or blocks, which maybe square, oval, or round, and which are usually tied, wired, orfastened together.

To this end our invention consists in certain novel features ofconstruction and peculiar combination of parts, all of which will behereinafter fully described in the annexed specification andparticularly pointed out in the claims, reference being had to theaccompanying drawings, in which Figure 1 is a perspective viewof ourimproved straw-burning stove. Fig. 2 is a 1ongitudinal section thereof.Fig. 3 is a horizontal section of the same, taken on the line 3 3, Fig.2. a

In the accompanying drawings, A indicates the stove, which may be formedof cast-iron, plate, or other suitable material, and constructed ofsubstantially the shape shown. In the front part of the stove isarranged the fire-box B, which is provided with a tilting grate D of anysuitable construction, such grate being preferably provided upon itsupper surface with prongs or spikesd for effectively stirring up thefuel when said grate is rocked. Below this grate is disposeda drafttubeE of any suitable but preferably conical form, which is provided with aperforated bottom 6, and which at one end registers and communicateswith a draft-opening 6, formed in the side wall a of the stove, andwhich is provided with a suitable cut-off slide e for regulating thedraft.

L denotes the ash-box.

F indicates the oven, located at the rear of the fire-box, which issurrounded by draftflues ff f f, as most clearly shown in Fig.

2 of the drawings. The flues f and f communicate at their lower end withthe fire-box B below the grate through an opening 6, which is providedwith adamper g. The upper end of the flue f (180 communicates with theflue f a damper G being provided at the juncture of said flues. By theaforesaid construction it will be seen that when the damper G is closedand the damper g is opened a portion of the hot air will pass up throughthe opening g, while the products of combustion will pass up over theinner wall W of the fire-box B and down and around the oven F, asindicated in arrows 1 1 in Fig. 2. It will also be seen that when anindirect draft is used the heavy particles of combustion will fall onthe inclined bottom 0 of the fuelchamber and be discharged through theopening g into the ash-box L. By closing the damper g and opening thedamper G a direct draft is obtained, as shown by arrows marked 2 2 inFig. 2. The upper front portion of the stove is extended forwardly, asat H, which forms a fuel-receiving chamber, the bottom of which isformed of a horizontal portion H and a downwardly-inclined portion H asmost clearly shown in Fig. 2 of the drawings. The front wall of saidchamber is composed of two hinged doors K K, which are provided withinwardly-extending flanges in 7a, as shown.

J denotes a gravity or swinging damper, which normally closes thecommunicating opening h between the fire-box and the fuelchamber H.

The manner of supplying the fuel to the stove is as follows: The fuel,which consists of compressed blocks of straw, flax, &c., is fed tofire-box by first opening the doors K and inserting one of the blocks inthe chamber H. Now, when the doors are closed in, the proj ections itwill push the block onto the inclined portion H and cause it to slidethrough the opening h, lift the damper J in its movement, and fall intothe fire-box B, the damper J fall ing back in place and closing theopening h, thereby cutting off communication between the fire-box andthe chamber II.

If desired, a supplemental chamber may be formed in the lower part ofthe stove to form a suitable receptacle for the fuel-blocks.

From the foregoing description, taken in connection with the drawings,the advantages of our improved stove will be readily understood, It willbe seen that the same is exceedingly simple in operation andconstruction, cheap as to cost, and very efiective for its desiredpurpose.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a straw-burning stove, the combination, with the fire-box, of afuel-chamber connected with the fire-box and disposed laterally thereto,and a door or doors hinged to the open end of said fuel-chamber,provided with inwardly-projecting portions, substantially as and for thepurpose described.

2. In a straw-burning stove, the combination, with the fire-box, of afuel-chamber connected with the fire-box and disposed laterally thereto,a gravity cut-0E damper for closing the opening between said chamber andfirebox, a door or doors hinged to the front Wall of said chamber,having inwardly-projecting portions, said doors adapted to push thefuel-block past the said gravity-damper when closed in, substantially asand for the purpose described.

3. The combination of the fire-box B, the

fuel-chamber H, provided with a downwardlyinclined portion, as H andopening laterally into the fire-box, a gravity-damper J, arranged at thejuncture of said chamber and fire-box, and doors provided withinwardly-extending projections arranged on the front wall of saidchamber, said doors adapted to push the fuel-' blocks onto the incline Hand past the gravitydamper J, substantially as and for the purposespecified.

4. The hereinbefore described improvements in straw-burning stoves,consisting of a fire-box provided with a lateral fuel-chamber at theupper end, doors hinged to the outer wall of said chamber, provided within- Wardly-projecting portions, as 70 k, adapted to push the fuel-blocksinto the fire-box when the doors are closed in, the draft-flue E,disposedbelow the grate of the fire-box, the oven F, fines f f f fcommunicatingwith the firebox, as shown, and the dampers G g,forchanging the directions of draft, all arranged substantially as andfor the purpose described.
